The name of the sake “Hakkaisan” is taken from one of the representative mountains in Niigata, which surrounds the brewery “Hakkaisan Sake Brewery.” “Hakkaisan” sake uses the underground water “Raiden-shinsui” (Raiden’s clear water) formed by the melted snow of Mt. Hakkaisan. The water source is known as a famous water source in Niigata, and the locals not only use it to brew sake but also to clean the brewing equipment and tools.
The philosophy of Hakkaisan Brewery is to brew high-quality sake that is delicious and not too heavy. The most challenging brewing technique for sake, “Daiginjo-shu,” is used in all sake products. During the polishing of the raw rice material, about two-thirds of it is removed to suppress yeast activity. The low-temperature fermentation process is used to make the aroma more robust, and the rice koji is handmade to complete the rich and delicious sake. Hakkaisan Brewery is committed to providing higher quality sake for more people to enjoy. Although the production line includes machines, they still try to manufacture it manually as much as possible, with the intention of brewing delicious sake.
